A hydrogel matrix for the storage, manufacture, functional testing, and viral infection testing of cellular moieties comprises 0.001 to 100m M gelatin, such as denatured collagen, and 0.01 to 1000 mu M of a cryoprolector, for example dextran. The matrix may further comprise 0.01 to 30 mM of a nitric oxide inhibitor such as an L-arginine analog. The hydrogel matrix may for example be used in treatments to increase vascularization. |
